50967cba95 Split the common C99/C++ support code out into a separate header.
Or, rather, add a new CIF-specific header, so tock_support.h is now the common
code and each of the backends has its own. This means some of the conditional
stuff can go away.

aff90d8d45 Some initial shuffling to get Tock working with the new CIF.
This changes the TLP code to use CCSP's stand-alone mode, and gets rid of the
old KRoC wrapper stuff. It also changes occam_stop everywhere in order to pass
the number of arguments (since ExternalCallN needs that now), and cleans up the
interaction with the C++ backend a bit.

acd57d74de Changed the A.Structured type to be parameterised
This patch is actually an amalgam of multiple (already large) patches.  Those patches conflicted (parameterised Structured vs. changes to usage checking and FlowGraph) and encountered a nasty bug in darcs 1 involving exponential time (see http://wiki.darcs.net/DarcsWiki/ConflictsFAQ for more details).  Reasoning that half an hour (of 100% CPU use) was too long to apply patches, I opted to re-record the parameterised Structured changes as this new large patch.  Here are the commit messages originally used for the patches (which, as mentioned, were already large patches):

A gigantic patch switching all the non-test modules over to using parameterised A.Structured
Changed the FlowGraph module again to handle any sort of Structured you want to pass to it (mainly for testing)
A further gigantic patch changing all the tests to work with the new parameterised Structured
Fixed a nasty bug involving functions being named incorrectly inside transformInputCase
Added a hand-written instance of Data for Structured that allows us to use ext1M properly
Fixed a few warnings in the code

1f8bb0e44a Removed the genVariable' function from GenOps
Now that the C++ generator no longer overrides genVariable', it seems wise to remove it from the GenOps function dictionary.

You can call it via either genVariable or genVariableUnchecked anyway, so genVariable' is just used by the two former functions as implementation.  It can easily be put back into the dictionary later on, if that turns out to be necessary.

9b96ea9899 Removed the C++CSP implementation of genVariable' by adding a new function (genDirectedVariable) that represents the only change from the C version (and added C and C++ version of genDirectedVariable accordingly) 2007-10-03 16:55:48 +00:00

8a2894893c Changed the GenerateC[PPCSP] modules to pass the current tests (just a matter of changing the spacing in the output) 2007-10-03 14:08:34 +00:00
Neil Brown
639b662a98 Starting making the spacing in the generated C and C++ code consistent, so that it passes the tests 2007-10-02 14:50:04 +00:00

15ecb2b178 Added the -fwarn-type-defaults compiler option (for when integer literals are given a default type) and fixed the few warnings that arose from doing so 2007-09-27 13:29:16 +00:00
Neil Brown
38c409d378 Added the -fwarn-unused-imports compiler option to warn about unused imports, and then set about pruning and ordering (mostly in my code) the import lists for all the modules 2007-09-27 13:13:46 +00:00
Neil Brown
8d95b65f00 Added support for the new AlternativeWait guards to the C backend
This was not as straightforward as the C++ backend.  CIF has no capability for supporting waiting *for* a specified time as an ALT guard; only waiting until (AFTER, in occam) a specified time.  This is further complicated by the fact that when you disable an ALT timer guard in CIF, you have to be able to supply the timeout value that you waited on in the enable sequence.

Therefore, I added a pass that transforms all WaitFor guards into WaitUntil guards, by declaring nonce time variables, getting the time, and adding on the delay that we want to wait for; these actions occur just before the ALT.

This new pass is in the new BackendPasses module, into which I also moved the identifyParProcs pass.  I also wrote tests for my new pass that live in the new BackendPassesTest module.

c97d1d00c8 Changed the error type from String to ErrorReport throughout the code
ErrorReport is of type (Maybe Meta, String), thereby adding an optional code position to error messages.

Die has been changed so that die and dieP are now implemented in terms of dieReport (:: ErrorReport -> m a).  This involved changing less code than changing die to be of type ErrorReport -> m a.  All that had to be changed directly was that Die instances now implement dieReport instead of die.

Any bits of code that "caught" errors has been changed so that it handles ErrorReport instead of String.  This ErrorReport is eventually, in Main, passed to dieIO, which will soon be changed to read the file in and provide the context.  Accordingly, MonadIO m has been added as a constraint to dieIO, and dieInternal has been changed to no longer use dieIO (because really we can't add the MonadIO constraint to dieInternal).

Various error messages have been changed.  Notably, all instances of fail in ParseOccam have been changed to use die or, wherever possible, dieP.  A similar thing has been done in EvalConstants and EvalLiterals.

3e342a621c Added ShowOccam and ShowRain type-classes, and changed existing code to use these new show methods in error messages
The function showCode shows code as either occam or Rain depending on the frontend.  This is then used by a formatCode function that acts similar to 
printf, which makes it easy to format error messages that use showCode.
2007-09-16 17:20:57 +00:00
Neil Brown
8af4a9f687 Added generation of forward declarations to the C and C++ backends.
These declarations are necessary for recursive functions/procs, so that the (forward) declarations are visible to the implementations.

Later on, the declarations could be moved into header files, which would allow multiple source files to be compiled (generating multiple header files) and linked together using the gcc linker.  Alternatively, external C/C++ programs could use code originally written in occam/Rain by including the header files.
